I have this problem with my PC. I tried using complete internet repair, completely scanned malware and adware (all clean now) and Kaspersky is currently running but still I cant access the internet on any browser or other applications - however I can ping websites like Google.
tried the winsock reset still no luck, uninstalled the network driver and restarted still the same. After some time, Mozilla gives up connecting it says "Secure Connection Failed".
Ok now I have decided to reset my windows 10, my applications were deleted but still I cant access the internet. I'm losing hope, maybe the nic is bad?
Update: I have double checked my cables using my rj45 tester, all seems to connect but the problem still persists.
Date and Time is set but still cant access
